What used to be considered pseudoscience by the scientific community but now isn’t?

Chiropractic is still pseudoscience. It’s essentially only the massage part that’s useful, and that doesn’t rely on chiropractic theory.

Although I agree with you that some chiropractic claims are ludicrous, let me ask you something: Have you ever had sciatica?

Because I have, 3 or 4 years ago, and it was excrutiating. Four or five chiropractic treatments, and it has not recurred.

I don’t care what their fringe beliefs are, I know when I feel better.
